TD1208R - TdSigfoxRfPower(14) seems to be 16dB

Even if the Power setting is set to 14dB on a TD1208R before sending a frame, the power consumption is 80mAh @3.3V looking like a 16dB transmission.
What is wrong ?
uint8_t m[4] = { MYTEEPI_HEADER_TEST, 0,0,0 };
TD_SIGFOX_RfPower(_state.currentTransmissionPower);
TD_SIGFOX_Send(m,4,2);

Sounds like I captured the current not the right place.
that's fixed, I've got :
TD_SIGFOX_RfPower(16);
=> 51mA avg
=> This one is ok according to the documentation

TD_SIGFOX_RfPower(14);
=> 49mA avg
=> This one is too high

is it the right way to set the rf power ?
